abstract = {The properties of biomembranes depend on the presence,
local structure and relative distribution assumed by the
thousands of components it is made of. As for animal cells,
plant membranes have been demonstrated to be organized in
subdomains with different persistence lengths and times. In
plant cells, sitosterol has been demonstrated to confer to
phospholipid membranes a more ordered structure while among
lipids, glycosphingolipids are claimed to form rafts where
they tightly pack with sterols. Glucosylceramides are
glycosphingolipids involved in plant signalling and are
essential for viability of cells and whole plant. The
glucosylceramide-sitosterol structural coupling within PLPC
membranes is here investigated by Langmuir films, in silico
simulations and neutron reflectometry, unveiling that a
strong direct interaction between the two molecules exists
and governs their lateral and transversal distribution
within membrane leaflets. The understanding of the driving
forces governing specific molecules clustering and
segregation in subdomains, such as glucosylceramide and
sitosterol, have an impact on the mechanical properties of
biomembranes and could reflect in the other membrane
molecules partitioning and activity.},
